The event will be held at the site of the future Southwest light-rail support facility in Hopkins. Invited guests include U.S. Sen. Tina Smith (D-Minn.), U.S. Rep. Keith Ellison (D-Minn.) and Hopkins Mayor Molly Cummings, while the hosts include Metropolitan Council Chair Alene Tchourumoff and Hennepin County Chair Jan Callison.

An extension of Metro Transit’s Green Line service, the $2 billion Southwest light-rail line will be Minnesota's largest infrastructure project. The 14.5-mile route will run from downtown Minneapolis through St. Louis Park, Hopkins, Minnetonka and Eden Prairie. The line will share a 7.8-mile corridor with the Twin Cities & Western Railroad Co. and BNSF Railway Co.

Heavy construction work is expected to start next year and wrap up in 2022, with light-rail vehicle testing to follow in 2022 or 2023.

The FTA’s finding makes the project eligible for federal reimbursement through the award of a Full Funding Grant Agreement, which is expected in spring 2019. The federal government is expected to provide $929 million for the project, with local dollars covering the remaining costs.
